CRG KT4 DD2 30 mm G-MG Hybrid

The CRG KT4 DD2 30 mm G-MG Hybrid is a high-performance racing chassis developed for drivers competing in direct drive and shifter classes who are looking for the perfect balance of grip, stability, and driving feel.

The chassis is manufactured from 30 mm and 32 mm chrome molybdenum steel tubing and features a unique geometry around the central fuel tank area.

This design provides excellent lateral grip and positions the chassis perfectly between a traditional 30 mm and 32 mm chassis. The KT4 DD2 Hybrid offers a highly predictable and responsive driving experience, particularly on slippery tracks and surfaces with low rubber build-up where mechanical grip is crucial.

The model is equipped with top-quality components, including magnesium wheels and magnesium hubs, the VEN 11 braking system, and the new 507/509 bodywork for improved aerodynamics and modern styling.

Rotax 125 Max DD2

The engine for everyone aged 18-100+.

What sets the Rotax DD2 apart from other kart engines is the absence of a chain and the smooth paddle shifters mounted directly on the steering wheel. Closer Racing After 15 years, Rotax introduced the major EVO update for the Rotax Max engine range.

The new engines retain the same crankcase and cylinder as before, but Rotax has added color to the crankcase and cylinder head for a more modern appearance. Performance remains the same, but consistency has improved significantly. The engine delivers peak performance straight from the factory. Thanks to the EVO update, the engine benefits from outstanding throttle response while previous issues with misfires and detonation have been eliminated.
